Comment on attachment 442838 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=442838&action=review Can we have a non-WPT test for our non-standard -webkit-mask-box-image-source causing `transform-style: flat`? (I know we don't implement the standard mask-border properties, and I see that they are almost completely untested in WPT.) Patch looks good otherwise, so a non-reviewer r=me with that. (Not sure if those test failures are real?) > Source/WebCore/ChangeLog:12 > + and `isolation: isolate` all force used style of preserve-3d: flat. Nit: `` around `preserve-3d: flat`, to be consistent with the rest of the sentence.
